Responsibilities

• Own end-to-end paid B2B campaigns across Google, LinkedIn, and Meta — from brief to creative to budget to optimization — with full accountability for CPL, ROAS, and CAC
• Manage and performance-manage an external performance marketing agency: set briefs, oversee execution, evaluate results, and hold them to the same bar you hold yourself
• Implement and maintain privacy-first tracking and attribution frameworks that work without relying on third-party cookies — Proton can't use invasive tracking, so you'll need to be creative
• Forecast quarterly budgets and KPIs, own the delivery, and report performance with clear insights and recommendations to the Performance Marketing Lead
• Identify and fix conversion bottlenecks across B2B funnels in collaboration with product teams across Proton Mail, Drive, VPN, and Pass
• Partner with the Ad Tech team to automate reporting and campaign processes, reducing manual overhead and improving data quality
• Drive creation of campaign assets across B2B product lines to acquire new business leads and clients

Requirements

• 4+ years of hands-on performance marketing experience with a clear focus on B2B user acquisition — not just brand or content
• Deep platform expertise across Google Ads, LinkedIn Ads, and Meta — you've managed significant budgets on all three and can optimize without hand-holding
• Proven track record of delivering measurable ROI (CPL, ROAS, CAC) through paid campaigns for B2B tech or SaaS products
• Experience managing an external performance marketing agency: setting briefs, overseeing execution, and holding them to results
• Comfortable designing and implementing privacy-preserving attribution — you've worked in environments where standard pixel-based tracking wasn't viable
• Strong Excel skills for budget forecasting, reporting, and tracking; able to derive clear, actionable insights from complex campaign data and communicate them to non-technical stakeholders
• Experience with marketing automation and lead nurturing tools (HubSpot or comparable)

Preferred

• Familiarity with CMS tools and landing page A/B testing
• Basic coding or automation skills for reporting efficiency
